power windows/sunroof wires

[Trevor Irwin]

the car is  a 1990 100

First, where is the power window harness? (somewhere tucked away under the
dash I'm guessing)

My real problem is this: the passenger side window switch won't operate
the power window, and the sunroof won't work. Now in both cases I have
figured out that the problem is a wire: in the window case, it is the
red/blue wire that connects to terminal 4 of the switch; in the
sunroof caes, it is the black/blue wire that connects to terminal 5 of the
switch. In both cases these are the wires that provide the juice. Now my
problem is that the window wire does not appear to be broken in the door
jamb as one would expect.

With the sunroof wire, I don't even have a guess where the break might be.
Now both wires ultimately hook up at the same place (Q10--plus connection,
in power window harness), but this doesn't seem to be helping me. All the
other windows work from their own swithces and all the windows operate
from the driver's side switches. Any suggestions would be greatly
appreciated. Thanks.
